. 1 This invention relates to electrical connectors and more particularly to a hood for the connector. :parts.

It is an ob ect o the pres nt nv n to pr vide a ho d f r an electr ca onnec pa t-whic is a ta he ereto thr u hhe polarizing term sthe connector par t t of play r l tive t t e pt itsel to the other 00 a be fix d to a pa l o It is anotherobjeot of .thepresent invention to provide a hood for a connector part which is adapted-to receive and retain a wire cablewherein the clamping. parts for therwire cable are'loosely secured to the main hood part and wherein the assembly is effected by projections on the respective clamping parts that pass into diagonally disposed openings in the main hood part and turned over inside of the main hood part to retain the clamping parts against outward displacement therefrom.

Other objects of the present invention are to provide a hood for electrical connector parts which is of simple construction, inexpensive to manufacture, easy to assemble upon the connec- Fig. 1 is-a collective view of the connector parts and the hood adapted for use on one of the connector parts.

Fig. 2 is a vertical sectional view of the hood connected to one of the connector parts and as viewed generally on line 22 of Fig, 1.

Fig. 3 is a side elevational view of the hood and connector part being positioned into a fixed connector part with portions of the hood broken away to show the lateral play permitted to the hood while making the insertion of the connector carried thereby into the fixed connector part.

Fig. 4 is an end elevational view of the hood and looking upon the clamp parts for retaining the wire cable.

Fig. 5 is a vertical sectional view of the hood taken on line 55 of Fig. 4.

Fig. 6 is a fragmentary sectional view taken through the clamp parts and the connection thereof with the main hood member and as viewed on line 6-6 of Fig. 2.

i2 -Referringnow to the figures, l0 represents: a connector part which has an insulating body H with a plurality 'ofmale terminals I2 connected thereto and havinghollow-ends [3 for receiving the respective wires of a cable It. This connector part also haspolarizi-ng male and female terminals I5 and 16 extending therethrough. The

male terminal l5 has a threaded shank I1 and a tapered outerend 18 avith a slot l9 therein adapted to receive a screw driver for efiecting-the connection of the connector part with hood 20. The female connector part 16 has a threaded shank 2| and its outer end is slotted at 22 to receive a screw driver for efiecting the connection of thisterminal with the hood 20. The-hood 2i! is formed of a main dished body or shell-member 23, Fig. 6, and clamp parts 24 and 25. The clamp parts are secured together about a cable armor 2'! by clamp screws 28. Each of the clamp parts has a projection 29. In the end of the shell 20 are holes 3| and 32 in diagonally opposite corners which receive the respective projections 29. The projections, upon extending through the openings, are bent over, as indicated at 33, to retain the clamp parts against outward displacement from the shell. A large opening 34 is provided in the shell member 23 at the end thereof for the purpose of receiving cable l4 and its armor 21.

The ends of the shell member 23 are cut away at 35 to receive the insulating block ll of the connector part 10. The sides of the shell member will thus extend over the sides of the insulating member to serve not only to retain the insulating member or connecting part, but also to guide the same during any lateral shifting movement of the connector part. The respective ends of the shell member 23 are provided with parallel slots 36 and 31 whereby to provide a bendable tongue 38 with a turned in end 39 having a threaded opening 40 therein. The threaded shanks of the terminal members [5 and [6 are screwed into the threaded openings 40 so as to tightly secure the connector part II) to the tongues 38. The tongues can be sprung laterally, as shown in Fig. 3, in order to permit the easy alignment of the connector part It] with a fixed connector part 41 in a wall or panel 42. The connector part Hi can accordingly float to a certain extent in order to allow for the alignment of the terminals with the connector part 41.

The shell body is made out of aluminum or its alloy and has sufficient resiliency or springiness for the tongues to normally center themselves and be returned to their initial positions when the pressure upon the hood and connector part has ceased.

The connection of the connector part 10 with the hood is a simple operation of merely turning the terminals l5 and 16 with a screw driver fitted into their respective slots. If polarizing terminals l5 and I6 are not used, an ordinary screw can be used for'efiecting the connection of this connector part to the hood.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims. 2

I claim:

1. An electrical connector part hood assembly comprising a shell member open at one end to receive a connector part, said shell member having opposing sides cut away from its open' end to permit the lateral shifting movement of the connector part relative thereto and providing side extensions to guide the connector part during any lateral shifting movement thereof, each of said ends being slit and providing a tongue adapted to be flexed inwardly and outwardly of the shell member, said tongue being adapted to receive fastening means on the connector part, said shell member having an opening removed from its open one end for receiving a cable.

2. In combination, an electrical connector part having an insulating block and polarizing elements disposed in the opposite ends of the block, connector terminals disposed in the block and extending from one side to the other thereof,

said polarizing elements having threaded shank,

portions and end slots adapted to receive a screw driver, a shell member having an open end to receive the connector part and opposing side portions cut away from its open end to permit the lateral adjustment of the connector part in the open end of the shell member and provided side extensions to guide the connector part during any lateral adjustment thereof, said side portions being further slit to provide shiftable tongues, said tongues being respectively bent inwardly and having threaded openings receiving the threaded shanks of the polarizing elements whereby to make secure the connector part to the tongues, said shell member having a cable opening for receiving a cable in order that its wires may connect with the connection terminals, and cable clamp means adjacent the cable opening and adapted to retain the cable within the opening of the shell member.
